Devices of this character have usually been 10 used. as a means. permitt ng a door to be opened slightly, but preventing the. same 7 from being further opened suiiiciently to permit unwarrantedentries into homes or buildings to which'the device issecured. De-

15 vices of thistypeheretofore known have usually been affixed to a doorand door-iambby screws, which screws, were left in an exposed position accessible to an unauthorized .entrant, and ithas been a simple expedient .20 to'etiec't an entrance with the employment of a screw driver'or the like to remove a ,portionof the safety device. I 7

With these objections in .view', it is ac cordingly an object of this invention to pro- 2 vide a safety hasp or" the class described having concealed securing means accessible only whenthe device is not in use. a

. Another object of thisinvention is to provide a'safety' securing device for a door or 30 the like having concealed securing means therefor, which means do not interfere with ease and proficiency in inounting the device. I A further object of the present invention is'to provide a novel method of mounting a device of the class described whereby the securing meansfor the device will he rendered inaccessible when the device .isin use. il urthere ie Qt thi -ie el ienis twe a do r h sh-qr e li e he w rlne me ns f r, hic ha s .m a le el tion to the hasp prior to the mounting of the same, and a fixed relation tov the ha'sp after the same is mounted. Other and further important objects of thisinvention will be apparent from the disclosures in the specification and accompanying drawings, I This inventionlin a-preferred form is illustrated in the drawings and hereinafter more fully described.

On the drawings: v

, Figure 4; is a View similar to Figure 3.

Figure 5 is a fragmentary horizontal sectional view taken substantially along line V-V of Figure 2.

FigureG is a fragmentary vertical sectional view taken substantially along line VI VI of Figure Figure 7 1s a fragmentary horizontal sectional view, similar to Figure 5, showing a modification of the present invention.

As shown in the drawings In the illustrated embodnnent of th s 111- ventlon there is shown a doorqamb 1 whlch is abutted by door 2. Secured to the doorjamb 1 is a hinged hasp 3 comprisinv a base plate 4, recessed as shown at 5, and folded back upon itself to provide a loop 6 to retain a pivot pin '7, and a slotted extended portion 8 pivotally mounted onthe pivot pin 7. Secured to thefdoor 2 is a casing 9 having a bolt or rod 10 fixedly mounted therein and extending theret-hrough, upon which extended portion is an enlarged head 11.

When the door 2 is closed as shown in Fig ure 1, the head 11 and the rod 10 are engaged inthe recess 5 with the hasp 3, and when'the portion 8, the hasp 3is pivoted adjacent the casing 9 the rod 10 with its enlarged head 11 will engage in the slot of the'portion 8.

Used: h r v ew el the r en invent on s the mean-5 for mounting the base plate 4: up n a do r-jamb 1 arms like. The upper portion of the base plate 4 extends rearwardly as, at 12 beyond the lower portion 13 of the base plate, and pivotally secured by the rivet lto the under side or inner face of the portion lQisan irregularly shaped plate 15. The bottom plate 15. is apertured as at 16 to accommodate the hidden screw a is e1 QP' V l, th an perture 18therein which isin alignment with an aperture 19 in the portion 12 of the base plate at when this portion 12 is positioned so as to totally obscure or conceal the bottom plate 15. Through the aligned apertures 18 and 19 a screw'20 is placed. It is to be noted that the rivet 14 1s made sl ghtly longer than necessary to allow sufficient play for the base Y plate l'to pivotwith respect to the bottom.

plate '15 when the latter has been secured 1n;

the mortised portion 21 of the door-j amb 1'.

The device hereinaboi'e described permits an easy and novel mounting or installing of the same. To install the hinged hasp' 8 a door-jamb or similar member is mortised as at 211and the bottom plate 15 is placed in the mortised portion, the base plate 4; pivoted withrespect to the bottom plate so as to eX- nose one of the apertures 16 as shown'in Figure "3 after whichthe-scre'wl'l is positioned. Then the base plate 4 is pivoted in the oppositewdirection to expose the other of the apertures 16, and the second screw 17 is positioned as shown in Figure l. t isto be noted that at this point in theinstallation of c the device, the entirehinged hasp 3 is securely aliixed to the. door-jamb 1 by the securement thereto of the bottom plate 15. .The' base plated is then pivoted until the, apertures 18 and 19 are in alignment, and the screw 20 is positioned through both the portion 12 of the base plate 4 and thebottom plate 15. (Simultaneously with the tighteningofthe screw 20 the base plate portion 12 will; be pressed into the mortised portion 21 oii'the jamb 1 so as to be flush therewith, and a clean and smooth exterior will be'presented as shown in Figures 5 and 6. When the device is mounted as just previously stated, the bottom plate 15 together with the screws 17 will be totally v g V I hasp comprising a base plate, a securing plate concealed by the portion 12 of the'base plate 4, and will be inaccessible'unless-the screw 20 is entirely removed to permit the base plate i to pivot upon the bottom plate 15.

However, when the slotted portion 8 of the hasp 3 isengaged by the bolt or rod 10 the base plate 1 is effectively preventedfrom any pivotal movement even though the screw 20 is removed, and the screws 17 through the bottom plate 15 will be inaccessible until the bolt '10 is disengagedfrom the member 8.

Obviously therefore, when a door is secured by the safety lock heremabove descr bed, due to the novel and nacesslble securing means of thehasp 3, an unauthorized person could not gain entrance by removinga portion of the lock, but could only do so by totally destroy- I ing a portion ofthe safety lock, which operation could only beaccomplished with great difliculty. H

The form of thisinvention disclosed in Figure? differs from the forms disclosed in Figures 1 to Ginclusive, only by the addition of a short 'flange 22 integral with the top portion of the base plate 4, and bent substanthe" spirit of this invention.

asers 2 tially at right angles thereto to extend ovcrthe inner'sidc of the door-jambl, in which position it is secured to the 'jamb' by a screw 23.

Toprovide the flange 22 the top portion 12 of thebase plate 4 is merely slit, when the recess 7 5 is provided therein, and the flanged portion is retained thereon, which portion is then bent V provide the recess 5 as in the. previously described form of this invention. Obviously,

this flange-secured upon the inner side of the j amb 1,:acts as an added safeguard, due to f its: inaccessiblev position, against the unau thorized removal of the hinged haspB.

' Obviously,of course, the improved mount ing means provided on the hasp disclosedin the] pi'esent invention may v be used upon hinges or the like without departing from From the foregoing it 1s apparent thatwe v if have provided a safety device fordoors and the like, possessing obvious advantages over previously known devices of this character, which advantages render the presentinvenfob tion substantially burglar-proof. Moreover, the device hereinabove described is composed V which may be formed a simple stamping operation, is easily assembled and may be very economically manufactured.

of few and simple parts,ithe majorityof V Vi e are aware thatmany changes may be made,and numerous details of construction may be varied through a wide range without departing from the principles of this invention,and we thereforedo not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art.
